Unsloth Studio's backend loaded Hugging Face model configurations with trust_remote_code=True, so selecting a model in the Studio UI, or requesting GET /api/models/config/{name} or /api/models/check-vision/{name}, executed Python code referenced by that repository's config.json auto_map. Studio ships in the PyPI unsloth package from 2026.3.5, and the issue was fixed in 2026.6.8 (commit 0533efe, PR #6391). The issue was reported by Pillar Security.
